large one began to fly on this date. He was particularly "sassy" and was ready to fight anything at the "drop of the hat". As they were sitting on the tent a crow came "cawing" over them. They both let out a defiant "duckhawk" war cry and did not seem to be in the least bit afraid. The smaller one died a few days later and from that time on I heard the older one utter the "duckhawk" yell only once. He seemed to his mate very much and spent most of the time gazing wistfully up into the blue. On July 23 or practically six weeks after they hatched, the oldest duckhawk was able to fly and after that I did to keep him tied to a long piece of fish line to keep him from flying away altogether.
